Meta-Analysis
BACKGROUND
Hypertension is an important risk factor for cardiovascular disease (CVD). Interventions with dietitians can help modify dietary intake and reduce hypertension risk.
OBJECTIVES
We aimed to examine the following research question: In adults with prehypertension or hypertension, what is the effect of medical nutrition therapy (MNT) provided by a dietitian on blood pressure (BP), CVD risk and events, and anthropometrics compared with standard care or no intervention?
METHODS
MEDLINE, CINAHL, and Cochrane Central databases were searched for randomized controlled trials (RCTs) published in peer-reviewed journals from 1985-2022. Risk of bias was assessed using version 2 of the Cochrane tool for RCTs. Meta-analyses were conducted using the DerSimonian-Laird random-effects model. Certainty of evidence (COE) was assessed for each outcome using the Grading of Recommendations, Assessment and Evaluation method.
RESULTS
Forty articles representing 31 RCTs were included and analyzed. MNT provided by a dietitian may reduce systolic [mean difference (MD): -3.63 mmHg; 95% confidence interval (CI): -4.35, -2.91 mmHg] and diastolic (MD: -2.02 mmHg; 95% CI: -2.56, -1.49 mmHg) BP (P < 0.001) and body weight (MD: -1.84 kg; 95% CI: -2.72, -0.96 kg; P < 0.001) and improve antihypertensive medication usage, relative risk of stroke (MD: 0.34; 95% CI: 0.14, 0.81; P = 0.02), and CVD risk score [standardized mean difference (SMD): -0.20; 95% CI: -0.30, -0.09; P < 0.001] compared with control participants, and COE was moderate. Additionally, MNT may reduce arterial stiffness (SMD: -0.45; 95% CI: -0.71, -0.19; P = 0.008) and waist circumference (SMD: -1.18 cm; 95% CI: -2.00, -0.36; P = 0.04), and COE was low. There was no significant difference in risk of myocardial infarction between groups. Dietitian interventions reduced BP and related cardiovascular outcomes for adults with prehypertension or hypertension.
CONCLUSIONS
Dietitians play a critical role in improving cardiometabolic risk factors for adults with elevated BP; thus, improved payment for and access to MNT services has the potential to significantly impact public health. This review was registered at PROSPERO as CRD42022351693.

UNLABELLED
Cardiovascular diseases and diabetes mellitus, debuting as arterial hypertension (AH) syndrome and prediabetes, are common types of chronic non-communicable processes, that are the leading cause of death in the world. The main treatment method for above mentioned disorders, according to the current guidelines, is pharmacotherapy. However, it is possible to effectively apply non-pharmacological correction methods, aimed at the probable etiological factor and inversive mechanism involved in AH maintenance, in the early stages when no permanent changes are maintaining a high level of blood hypertension (BH) and glycemia. Frequently, this mechanism is hypoxia in the vertebral arteries system due to cervical spine osteochondrosis.
OBJECTIVE
To evaluate the therapeutic effect of non-pharmacological methods of restoring brainstem blood supply in patients with AH and prediabetes.
MATERIAL AND METHODS
The number of patients equal 125 (57 men and 68 women, mean age 63.3±11.5 and 65.4±11.8 y.o., respectively) with prediabetes and 1st degree of AH without target organs damage, among whom 102 patients with prehypertension or 1st degree of hypertension and 24 ones with 2nd degree of hypertension, were examined. The original method of manually restoring brainstem blood supply developed in the Shishonin's Clinic was applied to all patients. The control group included patients with the same disorder, who did not receive manipulations. Blood pressure (BP) measurement, ultrasound and triplex ultrasonography of vertebral arteries, biochemical blood test, and estimation of glycemia and glycated hemoglobin were performed.
RESULTS
All patients of the study group had decreased levels of systolic BP (by 23.8±10.7 mm Hg for men and 32.8±11.9 mm Hg for women), an increase of flow velocity in vertebral arteries (by 20.6±7.5 and 21.5±7.2 cm/s, respectively), a decrease of glycated hemoglobin concentration (by 0.32±0.51 and 0.34±0.41%, respectively). In the comparison group, there were no patients with improvement in these indicators.
CONCLUSION
The effectiveness of the author's manual method of cervical spine osteochondrosis correction in the reduction of BP and glycemia levels in the early stages of the disease is shown.

BACKGROUND/OBJECTIVES
In the last 20 years, hypertension has become more common among younger age groups. Based on a global meta-analysis, the combined prevalence of hypertension and prehypertension were 4.0% and 9.7%, respectively. This study aimed to evaluate the prevalence of prehypertension and hypertension among university students and their associated risk factors.
METHODS
Four hundred and eleven students aged between 18 and 25 (196 males and 215 females) were randomly selected to participate from the College of Medicine and Medical Sciences (CMMS) and the College of Business Administration, Bahrain. The data was collected through a structured questionnaire, which gathered information about lifestyle habits. Trained students measured the participant's blood pressure and body mass index (BMI) according to standardized settings. All risk factors were studied according to the study field and their gender.
RESULTS
The mean age of the participants was 16.4±0.9 years. Of the total participants, 61.3% (n= 252) were normotensive, 30.7% (n= 126) were pre-hypertensive, and 8% (n= 33) were hypertensive. The prevalence of hypertension and pre-hypertension was higher in male students, 13.8% (n=27) and 44.9% (n= 88), compared to female students, 2.8% (n=6) and 17.7% (n=38), respectively. The results of the univariate analysis showed an association of hypertension with the field of study, gender, age, BMI, exercise frequency, frequency of eating junk food, and family history of hypertension (p < 0.05). Multivariate logistic regression analysis found a significant association between hypertension and pre-hypertension with gender, the field of study, and BMI.
CONCLUSIONS
The findings of the study revealed that hypertension and pre-hypertension are common among university students in Bahrain. The risk factors for these conditions include studying medicine, being male, and being obese.

BACKGROUND
Limited data are published on the relationship of Chinese visceral adiposity index (CVAI) with prehypertension progression or regression. Therefore, we investigated this association through the China Health and Retirement Longitudinal Study.
METHODS
Participants with prehypertension were assigned to two groups according to baseline CVAI, and after 4 years of follow-up, their blood pressure was analyzed for deterioration or improvement. We constructed logistic regression models for assessing the association of CVAI with progression or regression of prehypertension. A restricted cubic spline (RCS) model was utilized for determining the dose-response association. Subgroup analysis and sensitivity analysis were also conducted.
RESULTS
The study included 2057 participants with prehypertension. During the follow-up, 695 participants progressed to hypertension, 561 participants regressed to normotension, and 801 participants remained as prehypertensive. An association was observed between a high CVAI value and a higher incidence of progression to hypertension and between a high CVAI value and a lower incidence of regression to normotension (OR = 1.66 and 0.58, 95% CI: 1.35-2.05 and 0.47-0.73, respectively). The RCS model exhibited a linear association between CVAI and prehypertension progression and regression (all p for non-linear > 0.05). The results of subgroup and sensitivity analyses agreed with those of the primary analysis.
CONCLUSIONS
A significant association was noted between CVAI and prehypertension progression and regression. Thus, as part of the hypertension prevention strategy, monitoring CVAI is crucial in individuals with prehypertension.

BACKGROUND
The prevalence of cardiometabolic risk factors (CMRFs) is increasing in sub-Saharan Africa and represents a serious public health issue. Accurate data are required to implement adapted prevention programs and healthcare strategies. Thus, the aim of this study was to estimate the prevalence rates of CMRFs according to the level of urbanization, age and gender in Gabon.
METHODS
A cross-sectional study was conducted in northern (Bitam), western coast (Libreville, Melen) and southeast (Koulamoutou) areas of Gabon using the World Health Organization's (WHO) stepwise approach for the surveillance of chronic disease risk factors. Participants over 18 years of age, without known underlying disease, living in rural and urban areas of Gabon were included. Sociodemographic, biological, and behavioral data were collected. Univariate and multivariate analysis were used to identify the CMRFs.
RESULTS
Of the 978 participants, 499 lived in urban and 479 in rural areas. Their median age was 38[28-50] years. Tobacco (26.1% vs 6.2%; p < 0.01) and excessive alcohol consumption (19.4% vs 9.6%; p < 0.01) predominated in rural than in urban areas, respectively. Urban dwellers had more often insufficient physical activity than rural people (29.5% vs 16.3%; p < 0.01). In total, 79.9% of participants aged under 54 years had a high blood pressure;10.6% of the younger participants had pre-hypertension. Metabolic syndrome was more frequent in women (21.7%) than in men (10.0%) (p < 0.01); 6.4% of men and 2.5% of women had a high Framingham score (p = 0.03). Finally, 54.0% of the participants had three or four CMRFs. The multivariate analysis showed that men were more likely to be smokers and to be at risk of pre-hypertension or high blood pressure (p < 0.01). Women were more likely to be obese or to have a metabolic syndrome (p < 0.01). Living in urban areas was also a risk factor for hypertension, diabetes, metabolic syndrome and high LDL cholesterol level.
CONCLUSION
The prevalence of CMRFs was high in the study population. Disparities were observed according to urban and rural areas, gender and age. National prevention and healthcare strategies for cardiometabolic diseases in Gabon should consider these observed differences.

Effectiveness of multi-component modular intervention among adults with prehypertension in a village of Dakshina Kannada district - a community-based interventional study - protocol.
INTRODUCTION
The Joint National Committee (JNC 7) report on Prevention, Detection, Evaluation, and Treatment of Hypertension, defined "prehypertension," as individuals with a Systolic Blood Pressure (SBP) in the range of 120-139 mmHg and a (diastolic blood pressure) DBP of 80-89 mmHg. Prehypertension is directly linked with hypertension which is a precursor of CVDs. Owing to its high conversion rate to hypertension, it is important to identify individuals with blood pressures in this category and bring about lifestyle modifications in them that can prevent them from being hypertensive and from developing cardiovascular diseases later in life.
METHODS
This randomized controlled trial will be done among the selected pre-hypertensive adults of all genders residing in Kateel Gram panchayat, Dakshina Kannada district, Karnataka. A baseline survey will be done initially to assess the level of prehypertension among the study population. To study the effectiveness of the intervention, 142 individuals will be randomly allocated using block randomization technique to intervention and control groups. A multi-component module (educational intervention) will be developed, validated, and administered to participants in the intervention group, while the control group receives standard care. Each participant will then be followed up once in four months till the end of the study period of one year to assess for changes in SBP, DBP, WHR, BMI, stress levels, and usage of tobacco and alcohol.
ETHICS AND DISSEMINATION
Institutional Ethics Committee approval was obtained from Kasturba Medical College in Mangalore, India. The plans for dissemination of findings include presenting at scientific conferences and publishing in scholarly journals.

The objective of the study was to determine the prevalence and determinants of ever-measured blood pressure, prehypertension, and raised blood pressure at national, state and district levels in India. We analysed data from the National Family Health Survey (NFHS-5), on 743,067 adults aged 18-54 years. The sample consisted of 87.6% females and 12.4% males. We estimated prevalence rates and determined adjusted odds ratios for various dependent variables related to blood pressure. Geographical variations were visualized on the map of India, and multivariate logistic regression was employed at state and district levels, with significance set at p < 0.05. The prevalence of ever-measured blood pressure varied widely, from 30.3% to 98.5% across districts, with southern and northern regions showing higher rates. Prehypertension affected 33.7% of the population, with varying prevalence across districts. Raised blood pressure was there in 15.9%, with notably higher rates in southern region (16.8%). Determinants included age, gender, education, wealth, lifestyle, obesity, and blood glucose levels. These findings demonstrate the subnational variations in blood pressure, can guide evidence-based interventions at the state and district level, towards reducing the burden of raised blood pressure and enhancing overall population health.

Background In light of escalating rates of childhood obesity, understanding the gender-specific correlation between body mass index (BMI) and hypertension has become crucial for effective public health interventions. This study investigates the interplay between BMI and hypertension among school-aged children, with a particular emphasis on gender stratification to identify distinct trends. Methodology A cross-sectional study was conducted with a diverse sample of 702 schoolchildren aged 5-16 years from a lower-middle-income school in urban Mumbai. This cohort consisted of 491 boys and 211 girls within the gender subset. BMI was calculated using height and weight measurements, while blood pressure readings determined hypertension prevalence. The children were categorized based on the Indian Academy of Pediatrics (IAP) growth chart BMI calculations and blood pressure percentiles. SPSS Statistics version 23 (IBM Corp., Armonk, NY, USA) was used for data analysis. Data were analyzed using the chi-square test, with p-values <0.05 deemed significant. Results The overall prevalence of overweight was 16.52%, with 15.89% in boys and 18.10% in girls, revealing no significant gender difference (p = 0.487). In terms of obesity, the overall prevalence was 10.83%, with 10.99% in boys and 10.34% in girls, revealing no significant gender difference (p = 0.823). The prevalence of pre-hypertension was 7%, exhibiting a significantly higher prevalence in high BMI males (overweight and obese) versus non-high BMI males (normal and underweight) (p < 0.001); however, no such difference was observed in females (p = 0.289). The prevalence of hypertension was 15.95% with a significantly higher prevalence in high BMI males (overweight and obese) versus non-high BMI males (normal and underweight) (p < 0.001) and high BMI females (overweight and obese) versus non-high BMI females (normal and underweight) (p < 0.001). Hypertension was significantly higher in children with high BMI (overweight and obese) compared to their non-high BMI (normal and underweight) counterparts. Conclusions In lower-middle socioeconomic strata schoolchildren in urban Mumbai, the prevalence of obesity and hypertension was alarmingly high, attributed to shifting lifestyles and unhealthy dietary habits. Hypertension rates were notably elevated among overweight and obese individuals compared to normal and underweight individuals. More than a third of both boys and girls with obesity were diagnosed with hypertension, emphasizing a concerning surge in hypertension cases among children. Prioritizing age-specific blood pressure assessments can facilitate early identification and timely interventions.

BACKGROUND
Consuming opioid agonists is a risk factor for cardiovascular disease particularly in intravenous heroin users. The monthly injectable extended-release opioid antagonist, naltrexone (XR-NTX) is an effective treatment for opioid use disorder. The impact of opioid receptor blockade through XR-NTX on blood pressure, a critical risk factor for cardiovascular morbidity, has not yet been characterized.
METHODS
The study evaluated the change in blood pressure during XR-NTX treatment among 14 patients who predominately used intravenous heroin and 24 patients who used prescription oral opioids, all with opioid use disorder. Blood pressure was measured in each patient immediately before the first XR-NTX injection and ∼two weeks after the first injection. The change in diastolic and systolic pressure was compared between the heroin users and the prescription opioids users using analysis of variance.
RESULTS
XR-NTX treatment was associated with significant decreases in diastolic blood pressure in the heroin group, but not in the prescription opioids group. Systolic blood pressure values in the heroin users showed a decline at trend level only.
CONCLUSIONS
Further research is warranted to replicate our findings and to determine whether XR-NTX effect is relatively specific to blood pressure or generalizes to other components of metabolic syndrome. Distinguishing between heroin and prescription opioid users could shed light on the unique clinical and pharmacological profiles of opioid drugs, particularly regarding their cardiovascular safety. This information can be useful in developing personalized therapeutic strategies based on the route of opioid administration.

Although changes in dietary sodium intake alter blood pressure (BP) in salt-sensitive individuals, pathophysiological mechanisms are still unknown. It has been reported that uromodulin is involved in sodium tubular transport, and genome-wide association studies pointed to gene as one of the most important gene candidates for arterial hypertension. Our aim was to analyze urinary uromodulin, salt intake and BP in 326 young middle-aged subjects (mean age 36±8 years, 49.4% male). In a subgroup of 175 individuals, ambulatory blood pressure monitoring and echocardiogram were performed. Uromodulin was determined by ELISA. According to the JNC-7 criteria, subjects were classified as optimal BP (n=103, men 72%), prehypertension (PHT) (n=143, men 43%) and hypertension (HT) (n= 80, men 38%). There were no differences in age, salt intake, estimated glomerular filtration rate, sodium excretion and uromodulin among BP groups. However, in PHT subjects, uromodulin was positively associated with fractional sodium excretion and negatively with 24-h sodium excretion and diastolic BP dip. These findings point to the effect of uromodulin on sodium reabsorption along the nephron and consequently circadian BP alteration in prehypertensives.
